What are harmful levels of ozone?
Harmful levels of ozone typically occur when concentrations exceed 70 parts per billion (ppb) over an 8-hour period. Prolonged exposure to ozone at these levels can lead to respiratory issues, aggravate asthma, and cause lung inflammation. It is important to monitor ozone levels to protect public health.
Where is the hole in the ozone layer situated and when was it first discovered?
The ozone hole is mostly over Antarctica. It was first discovered in 1984.
Why should you continue to monitor the ozone?
It is a measure of depleting chemicals. We have staff near the South Pole, and they can do this monitoring too.See "What makes scientists think the ozone layer is thinning?"
Is net ozone uniform over the globe if yes why?
No, the distribution of ozone in the atmosphere is not uniform over the globe. Ozone levels vary due to factors such as sunlight intensity, temperature, altitude, and atmospheric circulation patterns. The ozone layer is typically thicker near the poles and thinner near the equator.
What would a scientist really need to do to determine the change in ozone over a year?
A scientist would need to collect data on ozone levels at regular intervals throughout the year using instruments like ozone monitors or satellites. By comparing the data collected over the year, they can determine the trends and changes in ozone concentrations over time. Statistical analysis can be used to quantify the extent of change and identify any patterns or anomalies.
Is the ozone hole constant over the time?
No the ozone hole is not constant over the time

Is there an ozone hole over Florida?
There is no specific ozone hole over Florida. Ozone depletion is a global issue primarily affecting the polar regions. However, elevated levels of ground-level ozone pollution can impact air quality in Florida, mainly due to factors like transportation emissions and industrial sources.
What is ozone accumulation?
Ozone accumulates over several hours, depending on emission rates and meteorological conditions.Therefore, for ozone to accumulate according to the photostationary-state equation, an additional pathway is needed to convert NO to NO2; one that will not destroy ozone.
What have the levels of ozone been like in the past 25years?
Ozone levels have shown some fluctuations over the past 25 years due to various factors such as emissions, climate variations, and environmental policies. There have been improvements in certain regions due to regulations and actions taken to reduce ozone-depleting substances. However, in some areas, ozone levels have remained a concern due to continued emissions from vehicles, industries, and other sources.
In 1985 ozone levels in the atmosphere over Antarctica seemed to be 30 percent higher than the levels found 10 years earlier?
Depends on the time of year. The levels of ozone vary by more than 70%, depending on time of year. Ugh, this doesn't help... >:( the answer is False, it is LOWERR!
What causes ozone pollution levels to increase?
The ozone is a pollutant at ground level. It is a greenhouse gas too. Phenomenon like lightening, smog etc increase ozone pollution levels to increase.Ozone in the lower atmosphere has three causes:Electrical discharges like lightningAs part of the photochemical smog creation processAs adown washing of stratospheric ozone as winds blow over mountains
Is the hole in the Ozone Layer growing?
Currently (2009dec23), there is no hole in the ozone layer at either pole. The maximum ozone hole size occurred in 2006. So it appears it is no longer growing.See "How did the ozone hole occur?" in the "Related questions" section below.
